Personally I think ITACHI would win merely because if you even glance into his eyes.. You'll be teleported into his nightmare realm and you can't just instant transmission out of your own fear... Am I right??
Goku blows up planets, Please, Tell me what the hell he's going to do without a planet? He kinda needs that.
Goku. Goku never loses. He also cheats. That sly little *****. If itachi used the mangekyo sharingan on him hed probably go super saiyan 4 and by some means of powering up to an unbelievabls tate he would escape. Goku be like pew pew pew with dat kamehameha and itachi go boom!
